Abstract

An electronic device includes a housing defining a through hole, a circuit board fixed in the housing, including a switch and a grounding portion connecting with the ground, a fastening member received in the through hole fixed on the housing and contacting the grounding portion, passing static electricity therethrough and defining a mounting hole, and an actuating member received in the mounting hole and contacting the fastening member, and pressing the switch when actuated; wherein the fastening member and the actuating member are conductive.

Claims

exact text as granted — not AI-modified
1. An electronic device comprising:
 a housing defining a through hole; 
 a circuit board fixed in the housing, comprising a switch and a grounding portion connected to ground; 
 a fastening member received in the through hole and fixed to the housing, contacting the grounding portion to allow static electricity to flow through the fastening member, wherein the fastening member defines a mounting hole; and 
 an actuating member received in the mounting hole and contacting the fastening member, pressing the switch when actuated; 
 wherein the fastening member electrically contacts the actuating member. 
 
     
     
       2. The electronic device as claimed in  claim 1 , wherein the actuating member includes a limiting portion disposed between the fastening member and the circuit board. 
     
     
       3. The electronic device as claimed in  claim 1 , wherein the fastening member includes a fastening portion protruding from the outside surface thereof to form a flange, the fasting portion further defining a plurality of fastening holes surrounding the mounting hole for fastening the fastening member to the housing. 
     
     
       4. The electronic device as claimed in  claim 3 , wherein a fixing portion protrudes from the housing, defining a fastening hole therein allowing the fixing portion to pass therethrough. 
     
     
       5. The electronic device as claimed in  claim 2 , wherein the fastening member comprises a discharge portion contacting the grounding portion. 
     
     
       6. The electronic device as claimed in  claim 5 , wherein the discharge portion is a cylindrical projection and disposed on the lower surface of the fastening member. 
     
     
       7. The electronic device as claimed in  claim 1 , wherein the outside surfaces of the fastening member and the actuating member are coated with conductive material. 
     
     
       8. The electronic device as claimed in  claim 1 , wherein the fastening member and the actuating member are electroplated plastic. 
     
     
       9. The electronic device as claimed in  claim 1 , wherein the fastening member and the actuating member are conductive material. 
     
     
       10. An electronic device comprising:
 a housing defining a through hole and receiving a circuit board; 
 a grounding portion connected to ground; 
 a fastening member received in the through hole, fixed to the housing and contacting the grounding portion to conduct static electricity thereto; and 
 an actuating member sleeved by the fastening member and contacting the circuit board when actuated; 
 wherein the fastening member electrically contacts the actuating member. 
 
     
     
       11. The electronic device as claimed in  claim 10 , wherein the fastening member comprises a discharge portion corresponding to and contacting the grounding portion. 
     
     
       12. The electronic device as claimed in  claim 11 , wherein the discharge portion comprises a cylindrical projection and is disposed on the lower surface of the fastening member. 
     
     
       13. The electronic device as claimed in  claim 10 , wherein a limiting portion is disposed on the outside surface of the actuating member and located between the fastening member and the circuit board to limit extension of the actuating member between the fastening member and the circuit board. 
     
     
       14. The electronic device as claimed in  claim 10 , wherein the outside surfaces of the fastening member and the actuating member are coated with conductive material. 
     
     
       15. The electronic device as claimed in  claim 10 , wherein the fastening member and the actuating member are electroplated plastic. 
     
     
       16. The electronic device as claimed in  claim 10 , wherein the fastening member and the actuating member are conductive material. 
     
     
       17. An electronic device comprising:
 a housing securing a circuit board and defining a through hole; 
 an actuating member, a first part of which protrudes from the housing and a second part of which contacts the circuit board when pressed; 
 a grounding portion connected to ground; and 
 a fastening member received in the through hole, fixed to the housing and contacting the actuating member and the grounding portion before the actuating member is actuated; 
 wherein the actuating member electrically contacts the actuating member. 
 
     
     
       18. The electronic device as claimed in  claim 17 , wherein the outside surfaces of the fastening member and the actuating member are coated with conductive material. 
     
     
       19. The electronic device as claimed in  claim 17 , wherein the fastening member and the actuating member are electroplated plastic. 
     
     
       20. The electronic device as claimed in  claim 17 , wherein the fastening member and the actuating member are conductive material.
